For Driven Pulleys that use Three Insert Buttons
All the plastic insert buttons must be in place at all times. Don't run the
system if any of the buttons are missing. Missing buttons will allow the
driven pulley to open too far and the belt will go down into an area of
the pulley where it's not supposed to go. If the belt comes in contact
with the rivets it usually damages the belt. In addition, the buttons also
keep the movable sheave from spinning, they reduce friction between
the cam and the movable sheave and they prevent metal to metal
contact, acting as shock absorbers so they play a very important role.
